Entity/Components based 2D engine written in C with embedded Lua scripts.
Engine written on my spare time. I wanted to do a game, ended up doing an engine ... again. Hey, engines are fun.
It is currently possible to load scenes with scripts and program shaders. You can run and load a scene :
scons -Q && ./bin/merriment
- Scons
- SDL2
- OpenGL (OS X only)
- chipmunk
- LuaJIT
- python2.7 (only required for the so-called "editor")
{
"entities": [
{
"components": [
[
"script",
{
"instance": {},
"path": "assets/scripts/player.lua"
}
],
[
"transform",
{
"angle": 0.0,
"position": [
0.0,
0.0
],
"scale": [
1.0,
1.0
]
}
],
[
"sprite",
{
"sprite": "assets/sprites/red_square.png",
"program": ["assets/shaders/vertex.vs", "assets/shaders/fragment.fs"]
}
]
],
"name": "test"
}
],
"path": "scene.mp",
"source": "scene.json"
}Install the python requirements from /editor/requirements.txt with
pip install -r editor/requirements.txt
It is possible to convert a json scene to msgpack format with the following command :
python editor/compiler.py
To unpack a scene :
python editor/decompiler.py
By default, compiler and decompiler will run through all the files of assets/editor/ or assets/scenes/.
In order to (de)compile only one file, the usage would be :
python editor/decompiler.py MSGPACK_FILE_PATH
or
python editor/compiler.py JSON_FILE_PATH
If you have already a running application, it is possible to hotreload a scene by pressing BACKSPACE.

It's jun for fun and for learning.
